WebCooling systems vary widely in efficiency but can be broken down into chilled water systems and direct expansion systems. Chilled water systems are generally more efficient and a rule of thumb for power consumption is 70% of the total peak load being supported. Direct expansion systems require about 100% of the total peak load being supported.
